[Flexradio] SDRConsole+delta44
Has anyone run the M-Audio Delta 44 with the last version of SDRConsole? I'm having no luck. It work fine with PowerSDR, of course. Richard W5SXD
Re: [Flexradio] SDRConsole+delta44
Richard, If you are talking about having problems with the source code, yes I too am having problems. Visual Studio 2003 will not open the 1.4.5.5B source code for me. 1.4.5.4B works fine. I will continue to look at it.

Re: [Flexradio] SDRConsole+delta44
Richard, The SDRConsole doesn't have the facilities to handle a 4 port card. Especially when considering that it doesn't have a proper Windows mixer. The original VB code (SDRConsole) relied upon the Windows mixer to switch between RX and TX. PowerSDR actually does the transitions for the Delta 44 in software (meaning, we do the mixing ourselves). Other things that would keep the SDRConsole from working with the newer cards is that we didn't have support for anything other than DirectSound in the VB version.

[Flexradio] New SDR Working on all Modes
I installed the jumper on my D44 Interface card, plugging in the mike andno audio. Drove me nuts. I fired up 1.4.4 and lo a behold, it worked on SSB! So I went back to 1.4.5 B4 to see what was different. The problem was, I had to disable VAC to work SSB. Makes sense! Anyway, had a nice QSO with VA3CWM, and even got an excellent audio report. So all is well. Thanks to everyone for the help and encouragment. John W2AGN
[Flexradio] WDM-KS Motorboats
I am using SR-40 hardware and the Creative Labs MP3+ USB soundsystem connected to my AMD Athalon64, 2800 laptop computer. Performance has been excellent on Previews 1 - 4 but the WDM-KS audio selection on Preview 5 caused motorboating on any signals above about an S7 in level. If I revert to either the MME or ASIO4ALL driver the motorboating issue dissappears. CPU utilization is about 30%. The physical configuration includes a physical connection between the right channel line out, of the MP3+, to the mic in on the laptop. This allows me to use the internal audio support to listen, via internal speakers, and to use MixW for digital decoding. The issues occurs with or without MixW running and is independant of the level settings on the internal SoundMax audio device. Not sure what other information to provide. 73 - Mike - K9JRI
[Flexradio] SR40 frequency error display corrected but....
Thanks for correcting the panadapter display range when a frequency correction has been applied for the SR40. An interesting by-product is that you can now see signals at least 10 kHz. outside of the actual tuning range that seem like they may not be actual signals but artifacts of signals from within the allowed 48kHz. tuning range. I will apply an external signal generator and try to quantify that issue. Youse guys do good work! (that was a common compliment from my old telephone company boss) 73 - Mike - K9JRI

[Flexradio] Wav file headers incorrect?
Hi, I do not own an SDR-1000 but had been looking at the powerSDR sources (thanks to Flexradio for making it GPL). I also downloaded the wav files available at the flex-radio website to make my own receiver on my GNU/Linux system with GNU Radio. As an intermediate solution for my testing, I thought of using the WAV files from flexradio and so started writing a wav file reader with gnuradio. I could play them file with Rocky on WindowsXP on my office machine. But when I tried looking at the headers of the wav files using ghex2 (a hex editor program available under GNU/Linux), it seems like they are incorrect. I tried just playing it with a normal WAV player just to verify the sanity of the WAV files but it refuxes to play, so I did some more stuff with Python.

Re: [Flexradio] WDM-KS Motorboats
Followup data: The connection between the MP3+ line out and the mic in on the laptop is not a part of the motorboating. Whenthe motorboatingoccurs it is present when listening via headphones connected to the MP3+ headphone jackand the connection to the laptop's mic in removed. It does still appear to be signal strength related. The motorboating sounds like a rough note rather than a pure tone on a CW signal.

Re: [Flexradio] Shiny new unstable branch
Phil Well, my 'hijacked' comment was not intended to be controversial. Hard to hijack anything which is right out there for the taking or modification, by anyone. (smile). My comment at the time, was the UI portion, however, I think you had re-written the underlying code in C#, if I'm not mistaken. Although CVS or SVN is an organized group effort without the necessity of having anyone 'in charge', so far, you as the originator of the 'shiny' concept and Bill as the only other 'first responder' are the only programmers to have commented. I think if you 'build it' they will come. Obviously you have written some or most of the underlying elemet(s) to get to the point where a GUI or some control panel, can be created. I have never given up on your original concept of a 'teaching' version in C# code and the hope that it could be done in an free IDE and other free tools. I know from Teamspeak that there are many others interested in the learning side of that equation. This would be a great venue for realizing that for many, including myself. My initial interest in the radio was to perhaps program some small part of it, learn, and get a sense of accomplishment. As I got more involved it just seemed natural to explore all areas of the concept. You certainly can 'jumpstart' this 'shiny new' option, with some plans, baselines, objectives modules, and code. I'm ready, anyone else 'on board'?

Re: [Flexradio] SR40 frequency error display corrected but....
This is a trivial fix -- The offending code is lines 7841 and 2 in console.cs - AdjustDisplayDataForBandEdge Corrected code is: double alias_free_low_edge_hz = (1e6 * soft_rock_center_freq) - DttSP.SampleRate/2; double alias_free_high_edge_hz = (1e6 * soft_rock_center_freq) + DttSP.SampleRate/2; I'm assuming Eric Waschman will pick up the change for the next release.

Hi,

It looks like the WAV file headers (some of the
values atleast) is
hosed. The 4th byte to 8th byte (counting from 0)
is supposed to show
the length of the file - 8, but it shows a
completely different value
when opened using a hex editor.
May be this is a bug (not so serious anyway..) but
may be I am
completely wrong. This mail is just to let you guys

Hi,
I do not own an SDR-1000 but had been looking at
the powerSDR sources
(thanks to Flexradio for making it GPL). I also
downloaded the wav
files available at the flex-radio website to make
my own receiver
[Flexradio] MixW
Well, I tried MMTTY, and got it working with SDR, but it is hard to tune. Tried out MixW, and it was a snap to tune. Even made a couple quick QSOs in the RTTY test with the SDR. Ended up sending my $50 for registration. Also got my K1EL WinKey working with N1MM logger, and of course, finally got SSB working (well, from the reports). So I am pleased that it only took a couple of days to get evrything working with the SDR-1000 as I wanted. John W2AGN
[Flexradio] 1 kHz snap to
It would be nice to be able to instruct the cursor to only stop at even 1 kHz positions whilst moving around the panadaptor display. An amazingly large number of ssb qso's are one 1 kHz boundries so tuning with the cursor would be a nice 'snap to' operation. Richard W5SXD
[Flexradio] CW Software Question
I would like to experiment with CW. What are the recommended software line up for a keyboard to CW program and a CW decoder that will work with the SDR1000. Thanks Dave
[Flexradio] Request for another VAC setting.
I've been trying to hook up CWGet to SDR-1000 using VAC and have run into a compatibility problem. CWGet only accepts audio at a sample rate of 11025 (one channel). Unfortunately, PowerSDR only supports 6K, 8K, 12K, 24K and 48K audio... Failing some other remedy (any suggestions?) I'd like to see 11,025 added to the list, but maybe making this a user-enterable field would be more flexible. (I honestly don't have any idea of the implications of doing something like this, so please excuse the request if it's really stupid.) Thanks, Mark
[Flexradio] Query re advantages/disadvantages of VAC
Perhaps a naive question but can someone please explain the advantages /disadvantages of VAC.? Yes it does do away with a second sound card, but it seems to bring in problems of comport conflicts especially with DXlab launcherT thanks Ross ZL1WN
[Flexradio] cw speed
version 1.4.5.5 delta-44: new keyer. Is the wpm suppossed to be correct? It seems to run at about 1/3 of the indicated rate. Primary:SDR Iambic ... dsp buffer 1024, audio 2048 Richard W5SXD
[Flexradio] USB port deactivated when MOX is depressed
I am using 1.4.5 beta preview 5, and when I depress the MOX, I get a USP port error. I checked several times and the USB adapter is checked in the setup menu, but after the error occurs the box is unchecked. Same problem with preview 4. I tried uninstalling, and then reinstalling 1.4.4, but now I get high a SWR message, even into a dummy load, the only difference here is that the USB port remains activated. I have been using the radio successfully for the last two weeks, and this problem just started today Could it be a hardware problem? Thanks, Ernie NY1N
Re: [Flexradio] MixW
Eric. Is it possible to get the RTTY working before too much longer? Includeing filters and FSK? Would also be great to have the desired signal to be place in the filter passband as with CW when clicking on it while in RTTY mode.

Re: [Flexradio] Wav file headers incorrect?
On 11/13/05, richard allen [EMAIL PROTECTED] wrote: In addition to reading the header, I can open the file in cooledit 2000 and listen to it. I can see the passband with the fft in cooledit and see cw signals flickering about. You may be looking at some of the numbers incorrectly. Remember that the four byte longs and the two byte shorts are in little endian (intel) format withe the least significant byte first. Thanks Richard for the insight. I will look at it again this evening. 73 -- Ramakrishnan VU3RDD
